The present invention appertains to new and useful improvements incircuit makers and breakers and more particularly to a novel timecontrolled switch, which in the present 6 instance is especially adaptedfor use in conjunction with radios, whereby radio receivers may be setin or out at some future time.

The principal object of the invention is to provide a simple andinexpensive switch :0 device adapted to be mounted to a clock structureand operated by the alarm mechanism thereof.

Another important object of the invention is to provide a novel timecontrolled switch which may be employed in conjunction with radioreceivers to predeterminedly set the same for operation at some futuretime.

These and numerous other important ob jects of the invention will becomemore a pparent to the reader after considering the invention asdescribed and claimed hereinafter.

In the drawings:

Figure 2 represents. a top plan view of an alarm clock with theinvention mounted thereon. 0 Figure 3 represents a fragmentarytransverse'sectional view of the clock structure showing the devicemounted thereon in end view.

Figure 4 represents a fragmentary longitudinal sectional view throughthe switch device.

Figure 5 represents a transverse sectional view through the switchdevice.

Figure 6 represents" a fragmentary plan moved.

Figure 8 represents a fragmentary and sec-- tional view of the means forsecuring the switch operating arm to the alarm winding stem.

Referring to the drawings. wherein like numerals designate like parts,it will be seen that the present invention is especially adapted for useon an alarm clock of the style as shown in Figure 1 and denotedgenerally by reference character 5. In Figure 2, the numeral G-indicatesthe usual alarm windin stem, while in Figure 1, the time winding stem isdenoted by numeral 7.

The present invention consists of a bracket 8 one end of which is curvedlaterally as at 9 and provided with a key slot extending inwardly fromits ends. This key slot is adapted to receive the protuberance 11usually provided for receiving the ring 12 upon the alarm clock, andthis end portion of the bracket is adapted for disposition between thetop surface of the clock and the collar 13 on the protuberance 11. Thebracket will extend in the direction shown in Figure 2 and upon thisbracket is secured a block 14 of dielectric material. The block isdenoted by the numeral 14 and has a triangular extension 15 beyond onelongitudinal side thereof.

As clearly shown in Figure 7, the block is provided with a longitudinalbore 16 and a slot 17, extending inwardly from the side of the blockopposite to the extension 15 and communicating with the bore 16 andextending longitudinally at the intermediacy of the block 14 as clearlyshown in Figures 1 and 7. At each side of the slot 17 a conductor pin 18is vertically disposed, being anchored suitably in the material of theblock for engagement with a switch arm 19 which is threaded at its innerend and engaged into the threaded opening in the slide shaft 20 which isslidably disposed within the longitudinal bore 16. This shaft 20 isadapted to protrude beyond each end of the bore and at one end isprovided with a stop pin 21 and a spring 22 interposed between the stoppin and the adjacent end of the block. The opposite end of the shaft 20is provided with a screw 23 between which and the shaft 20 may beprovided a conductor 24 leading from the radio receiver.

A switch arm 25 is pivoted as at 26 to the top of the block and to theapex of the triangular portion 15 and secured to the arm by the screw 26is a conventional wire 27 leading from the receiver. The free end of thearni 25 is provided with an actuating knob 28, and as shown in Figure 2,the conductor pins 18 areexposed through the top of the block forengagement by the arm 25.

The outer end of the alarm winding stem 6 is adapted for engagementwithin the threaded socket 29 of a T-shaped body 30, through theelongated portion of which the bore 31 is provided for adjustablyreceiving an elongated arm 82. A set screw 38. is engageable through theside wall of the elongated portion of the T-body to bite into the arm 82to retain the same-in a predetermined adjusted position. This adjustedposition must be so that the upper free end portion of the arm 32 willengage the switch arm.19 when the alarm mechanism is released to shiftthe switch arm toward the distal contact pin 18 and should the arm 25 bein contact with the said distal contact pin, the receiver' circuit willbe completed. Should the arm'25 be in contact with the other contact pinwhen the arm 32 is'operating, the receiver circuit will be broken by thedisplacement of the shank 19 from contact with said pin. Stop members 34are provided upon the blocks to limit the movement of the arm 25, saidarm is also provided with a detent for engagement with a recess in thebody 36, v

countersunk in the top of the dielectric body 14.

It will thus be seen that the present invention presents a simple andinexpensive switch mechanism for clocks. which is especially adapted forregulating radio receivers over predetermined time periods. It is alsoto be understood that various changes in the specific shape, size andmaterials may be resorted to, without departing from the spirit or scopeof the invention as claimed hereinafter.

What is claimed is:

1. A switch mechanism comprising a pair I of spaced contacts, a manuallyoperated switch arm movable into engagement with engagement with eitherone ofsaid contacts, v

said switch arm having means for attachment to an electrical conductor,a rod 'slidably sup- 7 ported in said block and having means forattachment to an electrical conductor, a switch arm carried by said rodfor engagement with said contacts, tensioning means normally positioningsaid rod with its switch arm in engagement with one of said contacts,and an actuating rod mounted on the said alarm winding stem of the clockmechanism and disposed rearwardly of the switch arm of the said rod forengaging and moving said rod in the direction of the other contacts uponactuation of the alarm mechanism, said actuating rod being adjustable onsaid stem.

In testimony whereof, I aflix my signature.

either of said spaced contacts, a shiftable switch arm between saidcontacts, control means normally holding said shiftable switch arm inengagement with one of said spaced contacts, and time controlled meansfor mechanically shifting said shiftable arm to dispose same inengagement with the other of A Q said contact.

2. A switch mechanism comprising a block of dielectric material having alongitudinal bore and a slot communicating with said bore and extendingoutwardly through a face of said block, contacts in opposite side wallsof said slot and disposed through a face of said block, a switch armmounted on said block and movable into engagement with either of saidcontacts, a rod slidable in said bore and having a switch arm disposedin said slot and extending outwardly of the said block,
